在对本申请提供的电子设备1进行介绍之前，先介绍超宽带(Ultra Wide Band，UWB)技术的天线的测角原理。请参阅图1及图2，图1为检测设备检测电子设备的位置的示意图；图2为图1中的检测设备利用UWB天线收发电磁波信号时的示意图。在本实施方式中，所述检测设备3可以为但不仅限于为手机、或平板等。所述电子设备1可以为但不仅限于为定位器(也称为可无线定位的标签)或具有定位功能的可穿戴设备(比如，手表、手环等)。所述检测设备3具有多个检测天线30。检测设备3对所述电子设备1相对所述检测设备3的位置检测时包括检测所述检测设备3与所述电子设备1之间的角度及所述检测设备3与所述电子设备1之间的距离。下面，对所述检测设备3检测所述检测设备3与所述电子设备1之间的角度的原理进行详细描述。在本示意图中，以P 1点表示其中的一个检测天线30的位置，以P 2点表示另一个检测天线30以P 3点表示所述检测天线30接收到的电磁波信号过来的位置；P 4点表示P 1和P 2连线的中点。在本实施方式中，θ 1表示P 1P 2连线与P 3P 1连线之间的夹角；θ 2表示P 1P 2连线与P 3P 2的连线之间的夹角；θ表示P 1P 2的连线与P 3P 4的连线之间的夹角；α表示θ的余角；D表示P 3P 4之间的距离；λ表示检测天线30收发的电磁波信号的波长；f表示检测天线30收发的电磁波信号的频率；d max表示两个检测天线30的间距的最大值。
其中，D远大于λ，则有θ 1≈θ 2≈θ。
由于所述检测天线30为利用UWB技术的天线，即所述检测天线30为UWB天线，因此：
f的范围为6.25GHz～8.25GHz；
相应地，
λ的范围为36.4mm～48mm，则有：
λ/2的范围为18.2mm～24mm。
d max＝18mm；
d 1＝d cosθ＝d sinα     (1)
电磁波信号达到检测天线30和另外一个检测天线30的时间差t 1为：
Figure PCTCN2022141334-appb-000001
其中，c表示光速，由于t 1表示电磁波信号达到一个检测天线30和到达另外一个检测天线30的时间差，因此，也称为到达时间差(Time Difference of Arrival，TDOA)。
电磁波信号达到一个检测天线30和达到另外检测天线30的相位差
Figure PCTCN2022141334-appb-000002
为：
Figure PCTCN2022141334-appb-000003
由于
Figure PCTCN2022141334-appb-000004
表示电磁波信号达到一个检测天线30和达到另外检测天线30的相位差，因此，也称为到达相位差(Phase Difference of Arrival，PDOA)。
Figure PCTCN2022141334-appb-000005
其中，α表示达到角度(Angle of Arrival，AOA)。由(4)可见，到达角度(AOA)α和到达相位差(PDOA)
Figure PCTCN2022141334-appb-000006
相关。
综上所述，检测设备3中的检测天线30的测角原理为：对于不同方向的入射的电磁波信号，到达电子设备1中的检测天线30中两个检测辐射体的路径不同，因此，引入了路径差，从而引入了到达时间差(TDOA)，从而引入了到达相位差(PDOA)
Figure PCTCN2022141334-appb-000007
通过到达相位差PDOA和到达角(AOA)α之间的唯一函数关系(4)可实现测角(即，检测设备3与所述电子设备1之间的角度)。
工业和信息化部关于UWB天线的使用的规定为UWB天线的发射信号的等效全向辐射功率频谱密度限值在6GHz-9GHz时为-41dBm/MHz。由此可见，这个规定限制了UWB天线的发射功率，因此，UWB天线较高的方向性会导致测距均匀不佳，具体表现在UWB天线在增益强的方向测距远，在增益弱的方向测距短。为了提高UWB天线的通信距离，有必要引入低方向性甚至全向性的UWB天线。相较于定向天线(即，具有较高的方向性的天线)而言，全向性的UWB天线的测距和测角效果更好。相关技术中的电子设备1中的UWB天线的全向较差，导致所述检测设备3对所述电子设备1的相对位置检测时测量效果不好。

在本实施方式中，所述多个第二射频信号中的每个第二射频信号的幅度相同，且相位相同；所述多个第二射频信号与所述第一射频信号的幅度相同，且相位相同。在其他实施方式中，所述多个第二射频信号中的每个第二射频信号的幅度相同，且相位相同；且所述多个第二射频信号与所述第一射频信号的幅度及相位中的至少一个不相同。本申请实施方式不限定所述第二射频信号与所述第一射频信号的幅度之间的关系，也不限定第二射频信号与所述第一射频信号的相位之间的关系，只要满足所述多个第二射频信号的幅度及相位均相同即可。
所述功分网络111包括馈电部1111及多个传输部1112。所述馈电部1111用于接收所述第一射频信号。所述多个传输部1112分别与所述馈电部1111相连且均匀环绕在所述馈电部1111的周缘，所述多个传输部1112中的每个传输部1112的长度相同，以使得将第一射频信号被分为多个等幅同相的第二射频信号，并将所述第二射频信号输出。换而言之，所述多个传输部1112均匀环绕所述馈电部1111设置且多个传输部1112中的每个传输部1112的长度相同，从而使得所述第一辐射体112上接收的所述第二射频信号的幅度相同且相位相同，进而使得所述第一辐射体112根据所述第二射频信号产生的第一电磁波信号的频段相同，且具有较低的方向性。换而言之，使得所述第一辐射体112根据所述第二射频信号产生的第一电磁波信号的频段相同，且具有较高的全向性。当所述电子设备1利用所述第一天线110与所述检测设备3进行通信以对所述电子设备1进行测距及测角时，测量效果较好。
所述多个传输部1112分别与所述馈电部1111相连且均匀环绕在所述馈电部1111的周缘，所述多个传输部1112中的每个传输部1112的长度相同，换而言之，所述第一天线110的馈电为中心馈电。在本实施方式的示意图中，以所述馈电部1111位于所述支架140的中心为例进行示意，在其他实施方式中，所述馈电部1111也可不位于所述支架140的中心。当所述馈电部1111位于所述支架140的中心时，便于所述功分网络111及所述第一辐射体112及第一耦合辐射体113的设置及制备。
所述馈电部1111一方面可调节所述传输部1112的特征阻抗与所述第一辐射体112的输入阻抗之间的匹配度，另一方面可便于所述功分网络111的加工。
在本实施方式的示意图中，所述传输部1112的数目为四个，因此，在本实施方式中，所述功分网络111用于将所述第一射频信号分为四个等幅同相的第二射频信号，可以理解地，并不应当理解为对本申请实施方式提供的传输部1112的数目的限定，在其他实施方式中，所述传输部1112的数目还可以为两个、三个、五个、六个、七个甚至更多。换而言之，所述传输部1112的数目大于或等于2个。
所述第一辐射体112可以为但不仅限于为激光直接成型(Laser Direct Structuring，LDS)辐射体，或者，柔性电路板(Flexible Printed Circuit，FPC)辐射体，或者印刷直接成型(Print Direct Structuring，PDS)辐射体、或者为金属枝节辐射体。
所述第一辐射体112的数目和所述传输部1112的数目相等，一个第一辐射体112电连接至一个传输部1112，且不同的第一辐射体112电连接至不同的传输部1112。当所述第一天线110用于收发第一电磁波信号时，所述第一辐射体112接收所述传输部1112传输的所述第二射频信号，并根据所述第二 射频信号产生预设频段的第一电磁波信号。在本实施方式中，所述第一天线110为UWB技术的天线，因此，所述第一辐射体112产生的信号也为UWB信号。所述UWB技术的第一天线110不是采用载波，而是采用纳秒至微秒级的非正弦波窄脉冲传输数据，因此，所占的频谱范围较宽，适用于高速、近距离通信。美国联邦通信委员会(Federal Communications Commission，FCC)规定，UWB技术的天线的工作频段范围从3.1GHz到10.6GHz，最小工作频宽为500MHz。目前主流的UWB技术的天线收发预设频段的第一电磁波信号时的中心频点为8GHz或者为6.5GHz。
所述第一辐射体112为单极子辐射体器。在本实施方式中，所述多个第一辐射体112均匀环绕所述功分网络111设置。在本实施方式中，每个第一辐射体112电连接的所述功分网络111的长度相同，且相邻的两个第一辐射体112之间的间隙相同。所述多个第一辐射体112均匀环绕所述功分网络111设置，从而使得所述多个第一辐射体112上形成相对均匀的圆形电流，进而实现较好的全向辐射。可以理解地，所述多个第一辐射体112排布的均匀性越好，所述多个第一辐射体112上越能够形成相对均匀的圆形电流(环形电流)，所述第一天线110的全向性越好。反之，所述多个第一辐射体112排布的均匀性越差，所述多个第一辐射体112上则不能够形成相对均匀的圆形电流，所述第一天线110的全向性越差。可以理解地，在其他实施方式中，所述多个第一辐射体112非均匀环绕所述功分网络111设置，这种情况下，虽然所述第一辐射体112的全向性相对差点，但，主要满足所述多个第一辐射体112间隔且环绕所述功分网络111设置，所述第一天线110能够形成全向天线即可。
可选地，在一实施方式中，所述第一辐射体112的数目和所述第一耦合辐射体113的数目相等，且相邻的两个第一辐射体112之间设置有一个第一耦合辐射体113。所述第一辐射体112的数目和所述第一耦合辐射体113的数目相等，且相邻的两个第一辐射体112之间设置有一个第一耦合辐射体113，可使得所述多个第一辐射体112及所述第一耦合辐射体113上共同形成相对均匀的圆形电流(环向电流)，进而实现较好的全向辐射。
在本实施方式的示意图中，以所述第一天线110包括四个第一辐射体112以及四个第一耦合辐射体113，且相邻的两个第一辐射体112之间设置一个第一耦合辐射体113为例进行示意，可以理解地，不应当理解为对本申请实施方式提供的第一天线110的限定。在其他实施方式中，所述第一辐射体112的数目也可以为其他数目，只要满足所述第一辐射体112的数目与所述第一耦合辐射体113的数目相等，且相邻的两个第一辐射体112之间设置有一个第一耦合辐射体113即可。比如，所述第一天线110还包括三个第一辐射体112、五个第一辐射体112、六个第一辐射体112甚至更多数目的第一辐射体112。此外，所述第一辐射体112的数目大于或等于2个，且所述第一辐射体112的数目和所述传输部1112的数目相等。
进一步地，所述第一耦合辐射体113与相邻的两个第一辐射体112之间的距离相同。
所述第一耦合辐射体113设置与相邻的两个第一辐射体112之间，且所述第一耦合辐射体113与其中的一个第一辐射体112之间具有间隙，所述第一耦合辐射体113与其中的另一个第一辐射体112之间具有间隙。在相邻的两个第一辐射体112之间的尺寸相同的情况下，所述第一耦合辐射体113与相邻的两个第一辐射体112之前的距离相同，即，所述第一耦合辐射体113与其中的一个第一辐射体112的之间的间隙等于所述第一耦合辐射体113与另一个第一辐射体112之间的间隙。所述第一耦合辐射体113与相邻的两个第一辐射体112之间的距离相同，从而使得所述第一辐射体112及所述第一耦合辐射体113上形成相对均匀的环形电流，进而实现较好的全向辐射。
所述第一天线110包括多个第一耦合辐射体113，所述多个第一耦合辐射体113均环绕所述功分网络111设置，且所述多个第一耦合辐射体113及所述多个第一辐射体112均位于同一圆上。
所述多个第一耦合辐射体113均环绕所述功分网络111设置，且所述多个第一耦合辐射体113及所述多个第一辐射体112均位于同一圆上，从而使得所述第一辐射体112及所述第一耦合辐射体113上形成相对均匀的环形电流，进而实现较好的全向辐射。
所述第一耦合辐射体113可以为但不仅限于为激光直接成型(Laser Direct Structuring，LDS)的辐射体，或者，柔性电路板(Flexible Printed Circuit，FPC)辐射体，或者印刷直接成型(Print Direct Structuring，PDS)耦合辐射体、或者为金属枝节的耦合辐射体。
所述第一耦合辐射体113设置于相邻的两个第一辐射体112之间，用于和所述相邻的两个第一辐射体112中的至少一个耦合，所述第一耦合辐射体113和所述第一辐射体112耦合，并形成耦合电流。本实施方式中提供的电子设备1通过设置第一耦合辐射体113，所述第一辐射体112及所述第一耦合辐射体113一起形成更加均匀的圆形电流，圆形电流可产生全向辐射，且可进一步降低所述第一天线110的方向性，使得所述第一天线110的全向性更好。
在本实施方式的示意图中，以所述至少一个第一耦合辐射体113为4个，且以所述第一辐射体112为4个为例进行示意，每个第一耦合辐射体113均设置于相邻的两个第一辐射体112之间为例进行示意，可以理解地，不应当构成对本申请提供的电子设备1的限定。在其他实施方式中，所述至少一个第一耦合辐射体113也可以为一个，两个，三个，五个，六个甚至更多个。所述至少一个第一耦合辐射体113的数目可以与第一辐射体112的数目相同，也可以与所述第一辐射体112的数目不相同。任意两个相邻的第一辐射体112之间的第一耦合辐射体113的数目可以相同，也可以不相同。当然，在一种实施方式中，在一对相邻的两个第一辐射体112之间存在第一耦合辐射体113，在另一对相邻的第一辐射体112之间不存在第一耦合辐射体113。在另一种实施方式中，当两对相邻的第一辐射体112之间都存在第一耦合辐射体113时，其中的一对相邻的第一辐射体112之间的第一耦合辐射体113的数目可以与另一对相邻的第一辐射体112之间的第一耦合辐射体113的数目相同，也可以不相同。当两对相邻的第一辐射体112之间都存在第一耦合辐射体113时，其中的一对相邻的第一辐射体112之间的第一耦合辐射体113的数目可以与另一对相邻的第一辐射体112之间的第一耦合辐射体113的数目相同，换而言之，相邻的两个第一辐射体112之间设置有同等数目的第一耦合辐射体113。当相邻的两个第一辐射体112之间设置有第一辐射体112时，相邻的两个第一辐射体112的数目可以为一个，也可以大于或等于一个。综上所述，所述第一耦合辐射体113的设置方式多种多样，只要满足所述第一天线110中包括第一耦合辐射体113，所述第一耦合辐射体113设置于相邻的两个第一辐射体112之间，且和所述相邻的两个第一辐射体112中的至少一个耦合即可。在本实施方式的示意图中，以所述第一耦合辐射体113的数目和所述第一辐射体112的数目相等为例进行示意，在其他实施方式中，所述第一耦合辐射体113的数目可等于所述第一辐射体112的数目，也可小于所述第一辐射体112的数目。相应地，相邻的两个第一辐射体112之间可设置一个第一耦合辐射体113，也可不设置第一耦合辐射体113。只要满足所述第一耦合辐射体113可和相邻的第一辐射体112中的至少一个耦合即可。
综上所述，本申请实施方式提供的天线组件10中第一天线110包括多个第一辐射体112，且所述多个第一辐射体112中的每个第一辐射体112均用于接收等幅同相的第二射频信号，且所述至少一个第一耦合辐射体113与相邻的第一辐射体112耦合，因此，当所述第一天线110工作时，所述第一辐射体112及所述第一耦合辐射体113上产生环形电流，即，使得所述第一天线110形成为全向天线。因此，所述第一天线110的方向性较低，全向性较好，当所述电子设备1利用所述第一天线110进行测距及测角时，测量效果较高。此外，由于所述第一耦合辐射体113电连接至所述电路板130的地极，因此，使得所述电路板130也参与辐射，进而使得所述第一天线110为垂直极化天线。所述第一天线110为垂直极化天线，即，所述第一天线110可收发垂直极化的电磁波信号。相较于水平极化的电磁波信号而言，垂直极化的电磁波信号在传输时受到地面等有耗媒质影响更少，传播距离更远。
需要说明的是，受工业和信息化部关于UWB天线的使用的规定为UWB天线的发射信号的等效全向辐射功率频谱密度的规定，本申请中提供的天线组件10的全向性较好，方向性较低，因此，本申请实施方式提供的天线组件10的第一天线110的增益较低。因此，在所述天线组件10所应用的电子设备1与检测设备3进行通信，以对所述电子设备1进行测距和测角时，可增加所述检测设备3与所述电子设备1进行通信的射频信号的功率，进而增加检测设备3的信号强度，由此可增加测距距离，提升测距及测角的测量效果，具有较强的工程实用性。

下面将结合仿真示意图，对本申请实施方式提供的电子设备1的通信性能进行说明。
请参阅图26，图26为本申请一实施方式提供的电子设备的天线组件中第一天线的散射参数曲线示意图。在本示意图中，横坐标为频率，单位为GHz；纵坐标为S参数，单位为dB。在本实施方式中， 所述示意图也称为S11曲线示意图。由本示意图可见，所述第一天线110的工作频段S11的数值小于-6dB的，即，约为7.85GHz-8.25GHz。由此可见，所述第一天线110具有较宽的带宽。此外，由本示意图可见，谐振频点约为8.0GHz，对应的S11的值最小，约为-9.5dB，因此，所述第一天线110具有较深的匹配深度，因此，第一天线110的辐射效率较高。综上所述，所述第一天线110在CH9频段具有较宽的带宽。
请参阅图27，图27本申请一实施方式提供的电子设备的天线组件第一天线的天线效率示意图。在本示意图中，横轴为频率，单位为GHz；纵坐标为效率，单位为dB。在本示意图中，曲线①为总辐射效率曲线，曲线②为第一天线110的辐射效率示意图。总辐射效率计算时考量到了辐射效率以及天线匹配等因素。由本示意图可见，所述第一天线110在CH9频段的天线效率较高。
请参阅图28，图28为图3中所示的电子设备中第一天线以及支架上8GHz面电流分布示意图。由此可见，所述第一辐射体112及所述第一耦合辐射体113上形成圆形电流，进而实现较好的全向辐射。由于所述功分网络111输出的第二射频信号为等幅同相的，因此，所述第一辐射体112及所述第一耦合辐射体113上可形成环形电流。换而言之，得益于来等幅同相的第二射频信号，所述第一辐射体112及所述第一耦合辐射体113上可形成环形电流。
请一并参阅图29及图30，图29为本申请一实施方式提供的电子设备的天线组件第一天线的在一视角下的辐射方向图；图30为本申请一实施方式提供的电子设备的天线组件第一天线在另一视角下的辐射方向图。由此可见，所述第一天线110的水平方向图接近一个圆，所述第一天线110的全向性较好，因此，在水平方向上的测距均匀性较好，提升测距及测角的测量效果，具有较强的工程实用性。具体地，在本实施方式提供的天线组件10中，所述第一天线110中包括第一耦合辐射体113，所述第一耦合辐射体113电连接至所述电路板130的地极，在所述第一天线110收发第一电磁波信号时，所述电路板130的地极也参与了辐射，因此，没有出现上面辐射强然下面辐射弱的情况(即，方向图不上翘)，而是方向图上下两面辐射较为均匀。
此外，由于所述第一天线110为全向天线，因此，当所述第一天线110水平放置时，得益于所述第一天线110水平面的全向辐射，可减低所述天线组件10应用于测距及测角时对测角算法的依赖，即，减少软件算法工作，具有较强的工程实用性。
请参阅图31，图31为本申请一实施方式提供的电子设备的天线组件第一天线的方向性示意图。在本示意图中，横坐标为频率，单位为GHz；纵坐标为方向大小，单位为dBi。由此可见，所述第一天线110的方向性在CH9频段小于2.3dB，最小为1.58dB,方向性很低，相应地，所述第一天线110的全向性较好。
请一并参阅图32及图33，图32为本申请一实施方式提供的天线组件垂直极化的方向图；图33为图32中所示的天线组件垂直极化的方向图。在图32及图33中，频率(frequency)为8HGz，辐射效率(Rad.Effic.)为-1.213dB，总辐射效率(Tot.Effic.)为-1.731dB，方向系数的绝对值(Dir.(Abs))为1.930dBi，Theta的方向系数(Dir.(Theta))为1.754dBi。按照图32及图33的坐标系，Theta方向的电场分量为垂直极化分量，Phi分量则为水平极化。由图32及图33可见Theta分量占比更大，因此天线辐射垂直极化波。
请一并参阅图34、图35及图36，图34中为一实施方式提供的天线组件的结构示意图；图35为图34中所示的天线组件的在一角度下的立体仿真图；图36为图34中所示的天线组件的在另一角度下的立体仿真图。在本实施方式中，所述天线组件10中的第一天线110的第一耦合辐射体113未电连接至地极。在本实施方式中，以所述传输部1112电连接所述第一辐射体112的部位与所述馈电部1111的中点的距离小于或等于6.5mm为例进行仿真。由图35及图36可见，所述图34中提供的天线组件10中的第一天线110为定向辐射天线。
请一并参阅图37及图38，图37为图6至图9中所示的天线组件的在一角度下的立体仿真图；图38为图6至图9中所示的天线组件的在另一角度下的立体仿真图。在本实施方式中，以所述传输部1112电连接所述第一辐射体112的部位与所述馈电部1111的中点的等于6.5mm为例进行仿真，由图37及图38可见，本申请实施方式提供的天线组件10中的第一天线110为全向天线。换而言之，当所述传输 部1112电连接所述第一辐射体112的部位与所述馈电部1111的中点的距离等于6.5mm时，所述第一天线110的全向性较好。
请一并参阅图39及图40，图39为图6至图9中所示的天线组件中的第一天线在一角度下的方向图仿真图；图40为图6至图9中所示的天线组件中的第一天线在另一角度下的方向图仿真图。在本实施方式中，以所述传输部1112电连接所述第一辐射体112的部位与所述馈电部1111的中点的距离等于12.5mm为例进行仿真，由图39及图40可见，当所述传输部1112电连接所述第一辐射体112的部位与所述馈电部1111的中点的距离等于12.5mm时，第一天线110的Phi分量为主，并且明显的观测到所述方向图中波束上翘，上侧辐射较强，下侧辐射较弱，全向性有待优化。
请一并参阅图41及图42，图41为图6至图9所示的天线组件中的第一天线在不同尺寸下远场方向系数随Theta的变化(Theta＝90)变化示意图；图42为图6至图9所示的天线组件中的第一天线在不同尺寸下远场方向系数随Phi的变化(Theta＝90)变化示意图。在本实施方式中，以所述传输部1112电连接所述第一辐射体112的部位与所述馈电部1111的中点的距离标记为PD_L。在本仿真图中，以第一天线110工作的频率为9GHz时进行仿真，在图41中，曲线①为PD_L＝4.5mm时的曲线；曲线②为PD_L＝6.5mm时的曲线；曲线③为PD_L＝8.5mm时的曲线；曲线④为PD_L＝10.5mm时的方向图；曲线⑤为PD_L＝12.5mm时的曲线。
在图41中，频率(Frequency)等于9GHz，主瓣幅度(Main lobe magnitude)等于-0.573dB，主瓣指向(Main lobe dirtion)为198.0deg，波束宽度(Angular width)(3dB)等于151.2deg，旁瓣电平为-3.5dB。
在图42中，曲线①为PD_L＝4.5mm时的曲线；曲线②为PD_L＝6.5mm时的曲线；曲线③为PD_L＝8.5mm时的曲线；曲线④为PD_L＝10.5mm时的曲线；曲线⑤为PD_L＝12.5mm时的曲线。
在图42中，频率(Frequency)等于9GHz，主瓣幅度(Main lobe magnitude)等于-0.822dB，主瓣指向(Main lobe dirtion)为341.0deg，波束宽度(Angular width)(3dB)等于120.2deg，旁瓣电平为-5.5dB。
由图41及图42可见，当PD_L较大时，Phi分量为主，所述第一天线110呈现水平极化。当PD_L较小时，Theta分量为主，呈现垂直极化。因此，当所述第一天线110为UWB天线，所述第一天线110收发的电磁波信号的频段为CH9频段，当所述传输部1112电连接所述第一辐射体112的部位与所述馈电部1111的中点的距离PD_L小于或等于6.5mm时，可确保所示第一天线110收发的电磁波信号为垂直极化，换而言之，可使得所述第一天线110具有较好的垂直极化性能。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型，这些改进和润饰也视为本申请的保护范围。
